Megger TM200 Digital Timer
Add precise timing to your relay and primary injection tests with the Megger TM200 Digital Timer. Designed for use alongside electrical test equipment, this compact instrument measures elapsed time using contact or voltage triggers.
The TM200 suits work with the Megger CSU600A current supply unit and ODEN A primary current injection test system. It also provides an additional timer for SVERKER 650 relay testing when more than one timing cycle needs to be measured.
With a rugged design and supplied carrying case, it is a practical choice for substation maintenance and industrial testing.

Why choose the Megger TM200?
✓ Add timing to your existing test equipment
The TM200 provides a dedicated timing function for use alongside a current source or relay test set. This is useful when your test arrangement needs an additional timer to measure an operating time.
Its applications include primary testing of protective relay equipment and low-voltage circuit breakers. The connected test equipment supplies the test current, while the TM200 measures the time between the selected start and stop signals.
✓ Match the timer to your test signals
Contact and voltage triggering give you flexibility when setting up a timing measurement. The timer accepts a maximum input voltage of 250V AC or DC.
In contact mode, it detects closed contacts at 0–1kΩ and open contacts at 4kΩ or above. These input specifications help you assess suitability for the equipment you intend to test.
✓ Take it between testing locations
The TM200 is intended for medium-voltage substations and industrial environments. It measures 194 × 115 × 49mm excluding the handle, making it convenient to position alongside other test instruments.
The supplied case keeps the instrument and accessories together for transport. The complete package weighs 2.8kg.

❓ Frequently Asked Questions (FAQ)
Q1: Which Megger instruments can the TM200 support?
A. Megger identifies the CSU600A, ODEN A and SVERKER 650 as applications for the TM200.
Q2: Does the TM200 generate the test current?
A. No. It measures timing. A separate current supply unit or injection test system provides the test current.
Q3: Does 1ms resolution mean 1ms accuracy?
A. No. Resolution describes the displayed increment. The specified timing accuracy is ±0.02% + 1 digit of the displayed value.
Q4: How is the TM200 powered?
A. It uses a 5V DC supply from the included AC/DC adaptor.
Q5: Can it work with contact and voltage signals?
A. Yes. Both trigger types are supported, with separate start and stop inputs.
